Tumblr
Tumblr's REST API v2 covers blogs, posts, likes, follows, and queue/draft management, plus a newer Neue Post Format for structured content blocks. Reading most public blog data only needs a registered app's api_key, but posting, reblogging, or acting on a user's behalf requires OAuth authorization. Both OAuth 1.0a and OAuth 2.0 are documented as currently supported, including a dedicated token-exchange endpoint for apps migrating from the older flow to the newer one.
AuthenticationOAuthRequires an OAuth flow; expect app registration.
